ATRA is usually well tolerated, but a few major side effects can be observed, ATRA syndrome (RAS) being the most important of them, potentially fatal. The manifestations of this Syndrome are fever, weight gain, pulmonary infiltrates, pleural or pericardial effusions, hypotension, liver dysfunction and renal failure. Material and methods: We studied to the 29 patients diagnosed in (January of 2002 - December of 2004) of acute promyelocytic leukemia (APL), which were treated with ATRA, all received the 45 dose of mg/m2/d . The diagnosis of the leukemia was made by citomorphologist analysis. The criterion of renal insufficiency, it was an increase of the creatinina superior to 20% of the basal level. The definition of the transretinoico acid Syndrome was based on the clinical criteria of Frankel. Results: Fourteen patients presented the Transretinoico Syndrome (48.3%), 11 of which (37.9%) died. The fundamental differences between the patients with or without ATRA were: fever (14 vs. 9, p=0,017), gain of weight (14 vs 0, p=0,000), pleural effusion (14 vs 2, p=0.000), pulmonary infiltrates (13 vs 1, p=0,000), cardiac failure (12 versus 2, p=0,000), respiratory distress (12 versus 4, p=0,003), presence of renal failure (10 vs 4, p=0,02), necessity of substitute renal treatment (6 vs 0, p=0,006) and arterial hypotension (12 vs. 3, p=0,001). The acute renal failure appeared in 10 of the 14 patients with SAR (71.4%), to 12±5 (1-25) days of the beginning of the treatment and their duration it was of 14±5 (1-46) days. Six (60%) needed substitute renal treatment and 5 (50%) died. Of the patients who survived, only a patient continues in dialysis. In both patient in that renal biopsy was made, the study showed signs of cortical necrosis. Conclusions: The appearance of acute renal failure in the course of the SAR is frequent, being observed deterioration of the renal function that needs substitute renal treatment in more than half the cases. The association of RAS with renal failure entails the high mortality (50%). The diagnosis and the precocious restoration of suitable the preventive measures and therapeutic are very important to avoid in possible the this serious complication of the treatment with ATRA. ER -
